In this second article we will see a practical application of the daisy-chained shift registers. We want to use four 7-Segments LEDs controlled by the Arduino board. As you can imagine, that is ...

When connecting the LEDs in parallel (you can power it from any direction) always start connecting the ground (gnd) before you connect the live (5v) power pin. There is so much you can do with WS2812B ...

This water sculpture can stop drops of water in mid-air. This is accomplished by flashing LEDs to illuminate the droplets at just the right time. But it’s not limited to blinky lights alone. … ...

Arduino Micro has some extra leds that it is tricky to programme. Like almost all Arduinos, has a built-in led - the green one on the left in the photo.

[Computergeek] made an Arduino Shield in order to use it as an Apple remote. We like the construction technique that he used; taking perf-board and soldering the circuit and using stripped wire to … ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
